Need help with input validation, loop logic

[mwr1976]

I have a pseudo battleship program. The user picks the size of the game grid, but it must be between 2 and 10 spaces square. I am having a brain fart(an extended one actually). I created a method to make sure the input was in the valid range. Which it does, but if the user puts in an invalid input twice it stalls. I thought my While loop while(validated) would keep re-looping so no matter how many incorrect answer the user gives it keeps telling him its invalid input, but it doesn't. I want it to keep telling the user that is invalid input until they input with in the correct range. Here's my code, thanks in advance!:

import java.util.*;


public class BattleShipGame 
{
	//Scanner object to take input from the user
	static Scanner console = new Scanner(System.in);
	public static void main(String[] args) 
	{
		//variable declarations
		int counter = 1;
		int gridSize = 0;
		int Xcoordinate = 0;
		int Ycoordinate = 0;
		char fireReturn = ' ';
		int bypass = 0;
		boolean validated;
		
		//Begin game statement and prompt user for input
		System.out.println("Welcome to the Battleship Game!");
		System.out.println("If you wish to quit at any time enter a -1 for a coordinate.");
		System.out.println("Please enter the size of the game board grid (at lease 2 but less than 11):");
		gridSize = console.nextInt();
		
		validated = validateRange(gridSize, 1, 11);
		 if(!validated)
		{
			System.out.println("Invalid entry! Enter a number between 2 and 10:");
			gridSize = console.nextInt();
			validated = validateRange(gridSize, 1, 11);
		}
		
		while(validated)
		{
			//Instantiates the gameboard
			String[][] gameBoard = new String[gridSize][gridSize];
		
				
			//fill game board with x's and place the battleship "B"
			LoadGameBoard(gameBoard);
			placeBattleShip(gameBoard);
			
		
				//Begin game loop
				while(Xcoordinate >= 0 && Ycoordinate >= 0)
				{
					System.out.println("Enter the X coordinate for your shot: " + "\n" + 
					                        "Remember the size of your game board is: " + gridSize + " X " + gridSize + "\n" +
								            "Your entry must be between 0 and " + (gridSize - 1));
						Xcoordinate = console.nextInt();
						
						if(Xcoordinate == -1)
						{
							counter--;
							System.out.println("Thank you for playing, you took " + counter + " shot(s)");
						}
						else
						{
						
							System.out.println("Enter the Y coordinate for your shot: " + "\n" + 
				                    "Remember the size of your game board is: " + gridSize + " X " + gridSize + "\n" +
						            "Your entry must be between 0 and " + (gridSize - 1));
							Ycoordinate = console.nextInt();
							
							if(Xcoordinate >= 0 && Ycoordinate >= 0)
							{
								System.out.println("FIRE!!!!   ZZZZZZRRRRRTTTTTCHHTTTTSHT");
								fireReturn = Fire(gameBoard, Ycoordinate, Xcoordinate);
							
							if(fireReturn == 'H')
							{
								System.out.println("Direct hit! you sank my Battleship!");
								System.out.println("It took a total of " + counter + " shots to win");
								printBoard(gameBoard);
								Xcoordinate = -1;
							}
							
							else if(fireReturn == 'M')
							{
								System.out.println("You missed, try again");
							}

								System.out.println("You missed, that position was a repeat, try again");
							}

								bypass = 1;
								printBoard(gameBoard);

						}//end of else for 1st coordinate condition	
							
				}//end of while "game loop"

You should change code statement
Line 26: if(!validated) to while(!validated)
Line 33: while(validated) to if(validated)
